This integrator module was designed to produce an analog signal to represent muscle activity.
The NL703 EMG Integrator module was designed to produce an analogue signal to represent muscle activity. The unit will accept signals up to ±1 V which it full-wave rectifies and applies to a leaky integrator. The output of the integrator is buffered and the overall gain is set at unity. The time constant of the integrator is set by a 6-position rotary switch. A toggle switch is also provided so that the direct signal can be viewed.
|Input||Maximum signal that can be processed without distortion is ± 1 V|
|Input Overload||Input is protected up to ± 75 V|
|Time Constants||Can be set to: 20, 50, 100, 200, 500 and 1000 msec; accuracy better than 10%|
|Integrate/Direct||Either Integrated signal or input signal is selectable by this switch; if Direct is selected, Integrator is reset to zero|
|Output||Output produces signal which has gain of unity from input but integrated with respect to time at time constant selected|
|Output Impedance||600O in integrate; connected to INPUT socket in Direct|
